To all whom it may concern.-

Be it known that I, ED IN J. LUMLEY, a subject of the Queen of GreatBritain, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Machines for MakingBullets and Shot; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in means for manufacturing bulletsand shot; and it consists in the novel instrumentalities which will befully understood from the. following description, taken in connectionwith the'annexed drawings, in which- Figure 1 is a side elevation of myimproved machine, parts of the frame of which are broken away and partsof which are in section. Fig. 2 is a top view of the twin sphericalbullet or shot forming rolls, showing their journal-bearings andgearing. Fig. 3 is a view in detail showing the shearing device, theguiding or sash frame for the verticallyreciprocating shear, and theshear-bed. Fig.- 4 is a sectional detail view showing a device foradjusting the knife G, and Fig. 5 shows in detail a portion of the bedor platen and one of the beveled side guides fora sheet of lead or othersuitable metal. 7

Referring to the annexed drawings by letter, A designates a frameadapted to sustain .the devices'which I shall hereinafter exdrawingscoiled or wound about the said roller. In front of this roller is ananti-friction roller a, the journals of which are sustained in notches aformed in the check of the main frame A. The perimeter of thisanti-friction roller a at its highest point is slightly above flush witha solid flat bed or platen b, which extends to and terminates at a pointas, hereinafter again referred to, and shown in dotted lines, Fig. 1.The object of this platen b is to cause the sheet of metal, after itcrosses the roller a, to lie flatly and evenly. In advance of the saidroller a,

I show twin rollers c c, the object of which is threefold: first, tospread the sheet or blank ribbon a evenly upon the bed I); second, tofeed this ribbon forward in the direction indicated by the arrows onFig. 1, and, third, to condense and compress the ribbon and prepare itfor a further process hereinafter explained. The highest point of thelower feed-roller o is slightly above the horizontal plane ofthe bed orplaten b, and this roller is journaled in bearings 0 bolted to thebottom of the top rails of the main frame A.

The upper roller 0 is practically the evener ters of the two rollers c care strictly parallel and in the same plane as the surface of the bed b.After the compressed sheet a leaves the said rollers I have found inpractice that it is liable to buckle up laterally. To obviate this,Iemploy side guides D, which are open sheath-shaped portions wedging andhaving laterally-overhanging lips d. At the point ac of these guides Dthe sheet of metal is cut into strips, as will be hereinafter explained.

On one end of the journal of the feed-roller c is keyed a ratchet-wheel0 the teeth of which are evenly spaced and pitched, as shown in Fig. 1.WVith the teeth of this Wheel engages a spring-actuated pawl 0 which ispivoted to a longitudinally-reciprocating lever 0 which is pivoted tothe main frame on the. stud e. is pivoted to a rod 0", which receivesvertical movement from an eccentric e on the horizontal transverse shaftB of a master gearwheel E. It will thus be observed that an intermittentrotary motion is imparted to the lower feed-roller from the said mainshaft. The main shaft B is journaled in boxes on standards B rising fromthe top rails of the The front end of the said lever main frame. Belowthe discharge-point a: of the guides D is a transverse hopper, which Ishall presently describe.

The standards B have on their inner sides tenons ff, (shown in Fig. 3,)which afford vertical guides for a knife-bearing frame G, which receivesvertical reciprocating motion from eccentrics g g, keyed on the mainshaft, acting through the medium of straps or links g. To this frame Gis suitably secured a knife G, which is adjustable and preferably setfor operation in the inclined position, my object being to cut the sheettransversely and squarely against a fixed blade G with a clean shearingaction. During this act of severing a shot-blank strip from the sheet atits free end will naturally drop. Now, for the purpose of presentingeach shot-blank strip evenly to shot-forming rolls II II, I employ mypeculiarlyconstructed hopper F, above referred to. This hopper is formedof an inclined rigid wall h and inclined wall 71, which is pivoted at7L2 to said rail and provided with an arm 1', that is acted on by aspring and bent to form a toe 1", that is acted on at proper times by atappet 7;, fixed to the shot-forming roll II. This shot-forming roll isjournaled in boxes supported by the lower bar of the frame A. On one endof the shaft of the said roll II is keyed a cog-wheel E, which engageswith the main wheel E, and which also in turn engages with an idler EThis idler engages with a cog pinion-wheel E, which is keyed 011 theshaft of the roll H.

The two rolls H II are provided with grooves 19, which, when each rollis taken diametrically, present a semicircle, the points 1) of bothrolls exactly coinciding, formin knifee, 1 edges which cut through andaid in condensing the metal without waste. I I I I I I 1 J is a:funnelfor; the; front roll II I his nnel is closely adapted to theseveral cor observed that one jaw of the strip-blank hopper F isactuated synchronously with the feed, the cutting-off device, and thefinal condensing-rolls II II. Instead of giving vibration to the wall hby a tappet 7c and the arm 2 this arm may be extended in an oppositedirection, so that it will be actuated directly by the cutter-frame,thus giving a more positive movement to the said wall and at the sametime a more sensitive movement. It will be observed that the rollers IIII are of the same diameter, and that these rolls are geared so that theroll 11 revolves more rapidly than the roll 11. The object of this isthat the strips or blanks are evened between these rolls and cut offsquarely. Should both rolls have the same speed, the blank stripsfalling between them might be cut obliquely and the material wasted.

If desirable, I may use a knife G, which, if desired, is adjustable forthe purpose of setting it more or less obliquely to regulate the cut ofthe shear, and also to nicely compensate for the wear and grinding ofthe knife, so that the several steps shall be strictly synchronous.

Of course it will be understood that the rollers c c are made of steeland sufficiently 95 :inthe samcdirection at :difierent speeds, as

specified. 1
